Implantation

I’m in my 2 week wait. I have Pcos so Ive had quite a few peaks in my cycle. We had sex every peak. A couple of days after the last peak I was sat down and had pulling in my lower abdomen on my right side. Would this be ovulation or implantation from the first peak?

With my first and second pregnancy I had a shooting feeling in my middle when I must have implanted. I’m wondering if it’s different this time or I was ovulating or what? Lol.
